SPRINGFIELD, Ill. – The speaker of the Illinois House took the first step Monday toward impeaching scandal-plagued Gov. Rod Blagojevich, appointing a committee to recommend whether he should be ousted after his arrest on federal corruption charges.

“We’re going to proceed with all due speed, but we’re going to make sure that what we do is done correctly,” said Speaker Michael Madigan, who often has clashed with fellow Democrat Blagojevich.

Once the committee makes a recommendation, the full House will formally decide whether to file impeachment charges. The Senate then would rule on the charges.

Blagojevich was arrested Tuesday on federal fraud and bribery charges, including allegations of a scheme to profit from his power to appoint a replacement for the Senate seat vacated by President-elect Barack Obama.

The state constitution gives lawmakers broad authority to impeach a governor for any reason they consider sufficient.

The governor, who remains defiant and returned to work Monday to sign a tax credit bill, had no immediate reaction to the impeachment committee, spokesman Lucio Guerrero said after Madigan’s announcement.

“Impeachment talk’s nothing new for this governor,” Guerrero said. “They’ve been talking about it for a long time.”

Indeed, Madigan said Monday his staff has been reviewing the legal possibilities for impeachment for about a year. His office produced a memo earlier this year outlining all the arguments legislative candidates could make in favor of impeachment.

Blagojevich’s administration has been under a federal corruption investigation for years.
